Steel Core Polyballs™

Stainless Steel CorePolyballs™

Metal Detectable | Invincible Core

When sifting screens break, Americule’s Stainless Steel Core Polyball™ will not pass through magnetic separators or metal detectors without being noticed.

Not only does this ball offer customers the same long-lasting, highly abrasion resistance as our standard Polyball™, but the steel core will never wear down, making it detectable at any stage of the ball’s life. It will always have enough mass to effectively set off a metal detector.

The physical properties of the premium grade polyurethane utilized in our Polyball™ offer a phenomenal improvement over rubber balls:


  • Solid Cast Thermoset Polyurethane
        Superior to all rubber compounds.
  • Stainless Steel Core
        Safe in most sifting industries, doesn’t wear down.
  • Extreme Abrasion Resistance
        Tremendous wear life reduces maintenance.
  • Non-Porous. Resistant to Oil, Moisture, and Chemicals
        Fights caking and build up. Will not deteriorate.
  • Optimum Rebound Resilience and Durometer (Hardness)
        Maximum cleaning action. Will not damage screens.
  • FDA Approved for Dry, Aqueous, and Fatty Foods
        No contamination, bacteriologically safe.
